GoLand 2020.3 Help

Run migrations

After you reviewed changes in the object source code, you can submit these changes to a database. When you press the Submit button (the Submit button) in the Database changes tool window, you see the Object Migration dialog. The Object Migration dialog displays a migration script for the object.

A migration script is code that changes all database or a part of it. You can use migration scripts to add or remove a column, upgrade the database version, or change column properties.

GoLand can automatically generate a migration script but you must check it before running.

You can use a migration tool for the following types of SQL objects: procedures, functions, views, materialized views, rules (PostgreSQL), events (MySQL), scripts (Exasol), triggers (except for PostgreSQL).

Generate a migration script

  1. Select two schemas, right-click any of them, and click Compare. Alternatively, select two schemas and press Ctrl+D.

  2. In the Diff Between <schema_1> and <schema_2> dialog, specify comparing options.

  3. Depending on the migration direction, click Apply Right to the Left and Apply Left to the Right.
